Metagenics D3 1000 gives you 1000IU of vitamin D3, in a convenient, easy-to-swallow microtablet for added convenience. This will help you to replenish your body’s vitamin D content daily – which is especially important in winter, and also often needed in the summer months as wearing sunblock can also prevent natural vitamin D from the sun’s rays reaching your skin. Vitamin D supplementation helps to combat depression and SADS (Seasonal Affective Disorder or the “winter blues”).
